Abstract
The utility model relates to a secondary waste gas treatment purifier, which comprises a primary purification tower, a secondary purification tower and a fan capable of pressing gas into the secondary purification tower from the primary purification tower. The primary purification tower is connected with a gas inlet of the fan by the aid of a pipeline, and the secondary purification tower is connected with a gas outlet of the fan by the aid of another pipeline. By the aid of the secondary waste gas treatment purifier, acid waste gas generated in industrial production can be further purified, so that finally emitted waste water and waste gas can reach atmospheric emission standards.
Description
Technical field
The utility model relates to the treatment of waste gas system, especially a kind of two stage treatment purifier to the acid waste gas that produced in production of polysilicon.
Background technology
Prosperity and development along with photovoltaic industry, increasing medium-sized and small enterprises begin crystalline silicon material is processed and handled, and most enterprise most when the silicon material is corroded all be to adopt the mixed liquor of nitric acid, hydrofluoric acid and hydrochloric acid to carry out the product corrosion, thereby will produce Main Ingredients and Appearance is the escaping gas of nitrogen oxide, a spot of hydrogen fluoride gas, a spot of hydrogen chloride gas and chlorine hydrogen silane, and the initial concentration of the sour gas that is produced is all at 150mg/m
3More than.And according to the requirement of " discharge standard of air pollutants ", when the aiutage height was 30m, the highest permission concentration of emission of secondary discharge standard NOx was 240mg/m
3, the highest permission rate of discharge is 4.4kg/h; The highest permission concentration of emission of secondary discharge standard HF is 9mg/m
3, the highest permission rate of discharge is 0.59kg/h; The highest permission concentration of emission of secondary discharge standard HCL is 100mg/m
3, the highest permission rate of discharge is 1.4kg/h, therefore, exhaust gas discharging concentration is respectively after the treatment and purification: NOX＜240mg/m
3, HF＜9mg/m
3, HCL＜100mg/m
3
At present, in order to reach this standard-required, processing mode to this type of sour gas on the market is to handle or other simple exhaust-gas treatment modes through the one-level wet purification, but, because the feature of a large amount of nitrogen oxide, hydrogen fluoride gas and the hydrogen chloride gas that are produced in process of production shows as burst, intermittent, and concentration is higher, so simple exhaust-gas treatment mode can't be real waste gas is improved comprehensively handled.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple in structure, waste gas purifying efficiency is high, final toxic emission concentration is little waste gas two stage treatment purifier is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of waste gas two stage treatment purifier, comprise first class purification tower, secondary purification tower and gas can be pressed into blower fan in the secondary purification tower from the first class purification tower, described first class purification tower is by the air inlet of pipeline connection blower fan, and described secondary purification tower is connected with the gas outlet of blower fan by pipeline.
Further, in order to reduce resistance, can make gas enter impeller more smoothly, and control the size of air quantity accurately, blower fan described in the utility model is the fiberglass centrifugal fan, blower fan is by variable-frequency motor driving work, and having in the blower fan by carbon steel is the impeller of skeleton, and the gas outlet of blower fan is provided with volume damper.
Again further, for waste gas can be filtered in the first class purification tower fully, be provided with the first corrosion-resistant water circulating pump, first spray equipment and the first filter packing device in the first class purification tower described in the utility model, the exit of described first class purification tower is provided with dewatering device.
Further, in order to make waste gas reach discharge standard, be provided with the second corrosion-resistant water circulating pump, second spray equipment and the second filter packing device in the secondary purification tower described in the utility model, the exit of described secondary purification tower is provided with takes off the mist device.
Again further, damage water pump and plug nozzle in order to prevent that foreign material from entering, the import department of first class purification tower described in the utility model and secondary purification tower is provided with gauze filter.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, the mode that adopts secondary purification to handle can further be carried out purified treatment with the acid waste gas that is produced in the industrial production, makes last waste water and gas of discharging can reach the standard of airborne release.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Among the figure: 1, first class purification tower; 11, dewatering device; 2, secondary purification tower; 21, take off the mist device; 3, blower fan; 31, volume damper; 4, gauze filter.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of waste gas two stage treatment purifier as shown in Figure 1, comprise first class purification tower 1, secondary purification tower 2 and gas can be pressed into blower fan 3 in the secondary purification tower 2 from first class purification tower 1, described first class purification tower 1 is by the air inlet of pipeline connection blower fan 3, and described secondary purification tower 2 is connected by the gas outlet of pipeline with blower fan 3.
All be provided with corrosion-resistant water circulating pump, spray equipment and filter packing device in first class purification tower 1 described in the utility model and the secondary purification tower 2, the exit of described first class purification tower 1 is provided with dewatering device 11, and the exit of secondary purification tower 2 is provided with takes off mist device 21.
